Tweakin' the chosen font:

Colours and 3d relief versions:

As with all decisions, its tricky when there's a couple of opinions in the mix, so after a band discussion, they decided to take the logo a different direction, so I roughed up these for debate and then the picked a font to go with and I went from there. Though I personally don't consider they final one finished, they were happy with it, so that's all that matters, but when they want colour or tweaks I'll be happy to do it :)
